Abstract

PURPOSE:To improve the winding workability of a stator winding terminal line by providing a terminal which is kept movable only in a single direction. CONSTITUTION:The winding end wire 4 is wound around the riser of a terminal 5 and electrically connected with the terminal 5 by soldering, welding, etc. Then the terminal 5 is pushed to move towards the winding terminal 3 and a stator 2 is forcibly inserted into a metal housing 6 of the electric motor and fixed. Thus the space F between the housing 6 and the terminal 5 can be secured, so that the axial dimension G of the housing 6 is miniaturized. In addition, the size H of the riser from the terminal block body 1, around which the winding end wire 4 of the terminal 5 is wound, can be measured on so large a scale that the workability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a terminal block for terminal processing of stator windings of an electric motor having a metal housing.

Conventional Technology In general, the terminals of the terminal block for stator winding terminal processing of electric motors are fixed components, and there is no structure that allows them to be moved or deformed even after winding terminal wires are wound and electrically connected. In order to ensure a spatial distance between the terminal and the metal housing, a housing with a large axial dimension is used, or a very small terminal is used, which makes it difficult to wind the winding terminal wire. Therefore, there has been a need for a terminal block for stator winding end processing that can reduce the size of the winding and has good workability for winding winding end wires.

Conventionally, as shown in FIGS. 4 and 5, a terminal block for processing stator winding ends of this type of electric motor has a terminal block main body 103 attached to the upper surface of a winding end 102 of a stator 101 by a method such as gluing.
is fixed, the winding terminal wire 105 is wound around the plurality of L-shaped terminals 104 and 107 provided on the terminal block main body 10, and an electrical connection is made by soldering or welding. The shape was incorporated into the housings 106, 109.

Problems to be Solved by the Invention In such a conventional configuration, as shown in FIG. 4, it is important to emphasize the winding workability of the winding terminal wire 106 and increase the rising dimension A of the terminal 104 from the terminal block body 103. There was a problem in that in order to ensure the spatial distance B with the metal housing 106, the axial dimension C of the housing becomes large.

Furthermore, as shown in FIG. 5, if emphasis is placed on reducing the size of the housing 109, it is necessary to reduce the vertical dimension E of the terminal 107 from the terminal block main body 11o. There was a drawback that the workability of attaching was poor.

The present invention is intended to solve these problems, and aims to reduce the size of the motor housing and at the same time improve the workability of winding the winding end wires of the stator.

Means for Solving the Problem In order to solve this problem, the present invention provides a terminal block main body fixed to a part of the upper surface or side surface of the winding terminal of the stator.
It has a terminal that is movably held in only one direction, and after winding the winding terminal wire around this terminal and making an electrical connection by soldering, etc., the terminal block for winding terminal processing is attached. It is constructed by moving toward the fixed end of the winding.

Function: With this configuration, when winding the stator winding terminal wire, the terminal stands up sufficiently from the terminal block body, and the winding work can be easily performed, and the electricity between the winding terminal wire and the terminal is After the terminals are connected, the terminals are moved toward the ends of the fixed windings of the terminal block main body, thereby ensuring a spatial distance between the motor housing and the terminals, and at the same time making the housing smaller. It becomes possible.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a terminal block main body, which is fixed to the top and side surfaces of the winding terminal 3 of the stator winding wound around the stator 2 with a resin such as adhesive or a tying thread. 1 holds a terminal 6 around which a winding terminal wire 4 is wound so as to be movable only in the direction of the winding terminal. In the above configuration, the winding terminal wire 4 is wound around the rising part of the terminal 6, and after the electrical connection with the terminal 5 is broken by soldering, welding, etc., the terminal 6 is closed as shown in FIG. The stator 2 is pushed and moved toward the end of the winding, and the stator 2 is press-fitted into the metal housing 6 of the motor.

As described above, according to this embodiment, the housing e and the terminal 6
A spatial distance F is ensured between the housing 6 and the housing 6.
The axial dimension G of the terminal 6 is reduced, and the rising dimension H from the terminal block main body 1 around which the winding end wire 4 of the terminal 6 is wound can also be increased, thereby improving workability.

Effects of the Invention As is clear from the description of the embodiments above, the present invention maintains good workability for winding the winding end wires around the terminals of the terminal block for stator winding end processing, and also reduces the size of the motor housing. This has the effect of making it possible to realize the following.
